Going solar in Nigeria has become an act of self-sufficiency in recent years. With the grid delivering unreliable power and rising costs resulting from the band reclassification, any business or household that could afford panels effectively unplugged, and the surplus those solar systems generated simply went to waste.

That has now changed, as the Nigerian Electricity Regulatory Commission has commenced its Net Billing Regulations 2026, a framework that allows electricity consumers to generate their own renewable power and sell the surplus back to the national grid. For the first time, there is a structured legal pathway for what the regulation calls prosumers — customers who both produce and consume electricity. 

Under the new rules, an eligible customer installs a solar system, uses what they need, and exports the excess to their distribution company. In return, exported electricity earns credits based on an export tariff approved by NERC, which are then set against future bills. If the value of what you export exceeds what you consume in a cycle, the remaining credit rolls forward. There’s a quieter sweetener too: prosumers keep any carbon credits their renewable projects generate.

It is not open to everyone. Systems must fall between 50 kilowatt-peak and 1.5 megawatt-peak, a benchmark high enough that this is, for now, a commercial-and-industrial story, not a rooftop-residential one. The process is deliberate: you apply to your DisCo for a technical feasibility assessment; it confirms that your installation meets standards and that the local network can absorb your exports; then you sign a Net Billing Agreement, register with NERC, and get fitted with a bidirectional meter that measures power flowing both ways. 

That feasibility step matters more than it sounds. Uncontrolled injections into a low-voltage network already prone to voltage instability and asset faults are exactly the risk that has shadowed distributed generation in Nigeria for years. 

Most coverage, including the framing you’ll see everywhere, calls this “net metering.” It isn’t. It’s net billing, and the difference is in how it works.

Under true net metering, your meter effectively runs backward, and every exported unit is credited at the full retail rate, a one-for-one swap where the grid acts as a free battery. 

Net billing is different: you’re compensated for surplus energy at a set export rate, typically lower than the retail price you pay for grid power. 

I know it sounds too technical, so let’s break it down. Think of the grid as a shop you both buy from and sell to. Under net metering, the shop swaps your unit for a unit. You hand over a kilowatt-hour at noon and take one back at night; no cash changes hands, and the price doesn’t matter. The grid is simply free storage that holds your power until you need it. 

Net billing works like a real shop: you sell your surplus at the shop’s buying price and buy back at the selling price, and the buying price is always lower. A unit you export is worth less than a unit you pull back in. So you run on your own solar while the sun is up, and only sell what you genuinely can’t use.

This was a choice by NERC, not an oversight, because the 1.5 MW ceiling is modest by international standards, which observers read as NERC’s intent to stress-test the framework with a defined first cohort before widening it. Net billing is the conservative, grid-protective design suitable for a network that can’t yet afford to treat itself as infinite free storage. It nudges prosumers toward self-consumption, efficiency, and eventually storage, rather than dumping the load onto fragile infrastructure.

The scale of the shift becomes clear in one number: as recently as 2024, grid-connected solar contributed roughly 0.2% of Nigeria’s total electricity generation. The capacity exists — Nigeria posted 141% year-on-year growth in new solar installs in 2025, making it Africa’s second-largest installer after South Africa. Net billing is the policy attempt to connect that latent capacity to the wider system, turning solar owners from passive off-takers into active contributors and earners.

The economics already lean in. Commercial and industrial solar users in Nigeria are seeing 20–30% savings compared to diesel self-generation, and an export credit only improves the math. Set against power shortages that cost the economy an estimated $29 billion a year in lost output, the case for pulling private solar into the grid writes itself. 

Here’s the catch: this regulation can’t solve it on its own: a prosumer model only works if both sides of the meter have total visibility.

On the utility side, a DisCo can’t credit exports it can’t measure, or absorb injections it can’t monitor in real time. On the consumer side, net billing quietly means that when export is credited below retail, the smart play is no longer “generate as much as possible” — it’s “understand your own consumption, maximize what you self-consume, and export the rest intelligently.” That requires visibility that most Nigerian energy users have never had.

This is the layer we’ve been building toward at Beacon Power Services. CAIMS maps the network into a digital twin, and ADORA runs real-time monitoring and billing on top of it, giving DisCos the operational picture that net billing depends on. And Xepp gives the consumer their half: a single app to track consumption patterns in real time, manage payments, and move on to solar with a system sized to their actual power use. Net billing makes that kind of consumption intelligence valuable in a way it simply wasn’t before.

Put plainly, the regulation creates the right to be a prosumer. The data and tools are what turn that right into a return.

The bottom line

NERC hasn’t flipped a switch that pays everyone for sunshine. It has done something more careful — built a controlled on-ramp that rewards efficiency, protects a stressed grid, and begins dismantling the one-way relationship in which power only ever flowed from the utility to you. Nigeria’s renewable market is projected to reach roughly 14 GW by 2031. Net billing is the signal that the country intends to capture that growth and share it with the people already paying to build it. 

The prosumer era is here. The question now is who can actually see well enough to make it pay.
